Chinook winds significantly impact the weather of the western Great Plains by acting as a distinctive winter phenomenon. These warm, dry winds descend the eastern slopes of the Rocky Mountains, often causing rapid and dramatic shifts in temperature.12

Specifically, a chinook can raise local temperatures by as much as 30 to 40 °F (17 to 22 °C) within a very short period, providing a temporary reprieve from the region's typically cold winter climate. These winds are a type of foehn wind, which is a meteorological event characterized by air warming as it descends from high elevations.21
